In the Advanced Materials and Processing Branch, Dr. Wohl is the technical point-of-contact and subject matter expert for surface engineering and interfacial science. He works closely with several other researchers from NASA Langley and the National Institute of Aerospace on several projects including: development of materials to mitigate insect adhesion to the exterior of aircraft to maintain laminar flow, evaluation of novel surface preparation techniques to improve adhesive bond durability and ageing properties for composite structures, and modification of seed material properties for use in wind tunnel experiments. Dr. Wohl leads research in his branch regarding development and modification of materials for dust adhesion mitigation involving several other researchers, a diverse set of scientific fields and an array of different research techniques. Dust adhesion mitigation enables reduction of damage to spacesuits, equipment, operation of mechanical parts, clogging of sensors, optics performance and resolution. This will be critical for space exploration missions involving operations in dusty environments such as Mars, the Moon, asteroids, etc. This work has led to publication in peer-reviewed journals, patent applications, collaboration with commercial entities and universities on related technologies.
